Does ESP8266 support Wi-Fi Direct?
Table of Contents
The ESP8266 module can be configured in your Arduino code either as an access point or it connects to an external access point. But this still requires network access to transfer data between the Arduino and Android device. Nb A Wi-Fi Direct android device will not see the ESP8266 as another Wi-Fi Direct peer.
How can I control ESP8266 without internet?

Can ESP8266 work without internet?
Firstly, it requires an internet connection so that the app can be connected to it’s server. Second, like other methods, the Blynk app as well as the Esp would have to connect to a WiFi Hotspot.
How can I control ESP-01 without a router?
To control the ESP-01 ESP8266 module without a router or an internet connection, the ESP-01 is placed into AP mode (Accesss Point mode). A smartphone or a PC with wireless capability is then used to connect to the module. Command codes are then sent to it thru a browser or an application.
Does ESP32 support Wifidirect?
The ESP32 supports WiFi Direct as well, which is a good option for peer-to-peer connection without the need of an access point. The WiFi Direct is easier to setup and the data transfer speeds are much better than Bluetooth.
What is Espnow?
ESP-NOW is a kind of connectionless Wi-Fi communication protocol that is defined by Espressif. In ESP-NOW, application data is encapsulated in a vendor-specific action frame and then transmitted from one Wi-Fi device to another without connection.
How do I connect my phone to my ESP8266 module?
Wi Fi Module ESP8266 – 3. Connect to Android Mobile
